This invention relatesto improvements in keyless locks and moreparticularly to locks designed for use on the vestibule doors of railwaycars and on the doors of railway car toilets, although it is capable ofa variety of other, usesalso. One, object is to provide a lock that willserve automatically to keep the doors locked, while the train is inmotion but that will permit them to be unlocked and opened when thetrain is standing still.

A further object is to provide a lock ofthis type that is positiveand'eificient in operation and durable in use. Vith the foregoing andother objects in view the invention consists in the combination andarrangement of'parts to be hereinafter fullydescribed, pointed out inthe appended claims and illustrated in the accompanying drawings whichform apart of this application and in which Fig. '1 is. a fragmentaryview of the vestibule door ofa railway car provided with the lock. e 1

-Li'ke reference characters denote correspondinglpart s throughout thesev'eralview's. The present typeof vestibuled railway cars is providedwith doors that are designed to be kept shu't while the train is inmotion and opened when the train is standing to permit loading andunloading of passengers. Quite frequently, however, a passenger willstep to the door while the train is in motion and open the vestibuledoors in order to getabetter view of the scenery or to .cool 0ft, to getfresh air orfor other purpose. -Not being accustomed to the roll andsway ofthetrain,

probability of serious injury or death and. at i missing his train. h ah I It is the purpose of the present invention to effectively guardagainst such occurrence and to this end thevves'tibule doors areprovidedwith locks thatcan be opened only when the train is standing orm oving very slowly, say miles per hour or less, ,7

The lock comprises a casing'having theside wallsl', 2, end walls 3, l, acover 5 having a recessed insert-,6, and a base 7 formed likewise witharecessed insert 8. Securedto the wall 3 by fastening means 9 is theangular bracket 10 the upper end of whichis pointed for disposal in therecessed-lug 11 carried by the table 12, the top surfaceof which isbeveled toward its center, whereby the same is sup ported foroscillation within the lock casing. Secured to and depending from the111icle1 side of the table, 12 are the, straps.l 3, 13 that convergetoward each otherand between them support the weight 14: disposed bestwith the practical. certainty of thereby beneath the pointed extremityof, the bracket 10 so that the table is disposed horizontally when notdisturbed by motion or vibration from, without. The table isofadian'ieter less than the distance between the walls 1, 2 in onedirection andl ess than the distance between the walls 3, t in atransverse direction so that while it can rock or oscillate freely uponits support it cannot become disengaged therefrom. a a

A'sleeve 15 extends transversely of the lock casing and through thewallslj, 2 and is open atone end, saidsleeve carrying the sliding bolt16, one end 1 7 fthereof. being diminished in diameter and dis'p osedinthe closedend of thesleeve 15 andencircled by an ea; ansion; eoilspring18 that abuts the shell der formed upon the bolt at the junction of itslarge and small portions said spring also abutting the closed end of thecasingso that it yi-eldingly projects the freeand concave end 19 of thebolt fr oin the open end of the sleeve. The sleeve 15 is formed with theoppositely disposed perforations 20 which are disposed in line with theperforations for the extensions 21 of the knobs 22, 23, one perforation2-1 in the wall 3 for the knob eX- tension 21 of knob 22 being shown inFig. 9.

The said bolt 16 is formed with a large perforation 25 bridged only bythe oppositely disposed strap-like portions 26, 27 and into saidperforation the integral. beveled portion 28 extends, the apex of thebeveled portion being disposed midway between the strap-like portions26, 27; The shaft that connects the knobs 22, 22-3 comprises the shank29 formed with a terminal head 30, a t-rouglilike portion s1semi-circular in cross section and receiving the said head 30, and thethreaded or grooved portion 32-upon which the knob is received andsecured through.

the medium of the screw 3 The trough-ii portion 31 of the knob shaftextends through the perforation in the bolt and through the sleeveperforations with its open side receiving the beveled portion 28 of thebolt as shown in Fig. 3 so that oscillation of the knob shaft in eitherdirection will cause the lateral edges of the trouglrportion 31 toengage with the bevel 28 and retract the bolt thus disposing it entirelywithin the sleeve against the tension of the spring 18. A cam or dog 34is secured by means of thepin 35 to the shank 29 contiguous to the head30 and to one end of the trough-like portion 31 of the shaft.

Refering now to the look as shown only in Figs. 1 to 9 inclusive thecover 5 is formed with a stop lug 36 that is disposed against the sidewall 2 just above a leaf spring 3'? secured at one end to said wall 2for engagement with the upper free end of an angular lever 38 ful crumedupon a pin 39 that connects a pair of spaced lugs lO, il secured to thewall 2, said pin extending through a perforation in the end wall 4 andbeing threaded to receive the retaining head 42. The said lever 88 isrormed with an integral toe 43 which 1s cusposed above the central pointof the beveled table 12 for engagement with a ball 4 1, freely disposedupon said table, when said table is stationary, said ball having thengravitated to the center of the table between the spaced guard pins 45,d5 which lie in a straight line connecting the walls 1, 2.

A sleeve 46 is adapted for disposal freely upon the shank 29 said sleeveat one end be ing formed with the large cam 47 integral with the smallsegmental portion l8, said cam 47 carrying a pin 49 upon the face remotefrom the sleeve 16, said sleeve being adapted for passage through theknobshaft-perforation in the casing wall at and being formed with aperforation 50, this end of said sleeve being received into thecxtension 21 of the knob 23, said members being secured together by ascrew passing into the said perforation 50 and through a perforation inthe said extension 21. A pin 51 also carried by said sleeve being spacedfrom the perforation 50 and being disposed upon the opposite side of thecasing wall 4; with relationto'the knob extension 21 is shown in Fig. 2.

When the sleeve 46 is in position upon the shank 29 the cam 47 iscontiguous to the dog.

8% so that said dog in its movement with said shank will engage with thepin 49. A coil spring 52 encircling the sleeve at has one end secured tothe said pin 49 and its opposite end to a pin 53 in the casing wall 4.In operation the bolt 16 to be retracted by the knob 23 winch is theinside knob as distinguisl'ied from the knob 22 which is located outsidethe door. "When the train is running the vibration and sway motion issufficient, unless the train is running at a speed of 15 miles per houror less, to cause the table 12 to tilt thus causing the ball ie; tomoveabout. Thespring 52 ser es yieldingly to retain the sleeve and camah, l? in normal position iliustrated in Fig. 5. Que edge of the cam isnow disposed against the stop lug 36 and it is engaged peripherally bythe upper end of the lever 38. By now turning the knob 23 in onedirection the sleeve, loose upon the shank 29, is rotated thus rotatingthe cam into the position shown in 7. The outer edge of the cam is nowdisposed in such posltlon that the lever 88 may move away from thecasing wall 2, the upper end of said lever being engaged by the portion48 of the cam the movement of that member being arrested thereby beforethe pin 4L9, which is disposed in the path of the dog 3% can operativelyengage said member. if an attempt is made to move the cam in tl eopposite direction it will ride into engagement with the lug 36 as shownin Fig. 5. Orcillation of the sleeve and cam by knob 23 new accomplishnothing. If the train is standing or running at so slow a speed that theball may center upon the table througl gravity and on account of thehorizontal position of the same the lever is will engage the ball and besupported or retained through such contact in upright position shown inFig. 6. The knob 23 may now be turned and the sleeve and camrotatedcausing the pin 48 to engage with the dog 34 and thereby rotate theshafts 29, 31, thus retracting the bolt. lVhen it is desired to hold thetable against oscillation so that the ball a l maycenterupon the tableeven though the train is in motion use is made of a rod 54 that extendsthrough the casing and is supported in'the top and bottom thereof andprovided with a lift lug 55 adapted, when the rod is raised slightly, toengage with one edge of the table to prevent oscillation thereof, saidrod being secured against accidental withdrawal from the casing by meansof the cotter pin 56.

In Figs. 10, 11 and 12 a modification is shown and this form of lock isadapted for use upon railway car toilet doors. In this instance it isdesired to permit the door to be unlocked and opened only when the trainis in mot-ion and the ball 44 thereby disturbed from the table center.The shank 29 is provided with the dog A fast thereupon and the sleeve 46and cam 47 are dispensed with. The knob 23 is used to open the door. Alever 38 formed with a cam head B is fulcrumed, upon the pin 39, thishead being of such size and weight it will normally cause the lever togravitate toward the table 12 or into the position shown in Fig. 11except at such time as said lever may be engaged by the dog A in whichposition it is yieldingly retained by the bolt spring 18. When the trainis standing and the ball is centered upon the table the head B of thelever 38 will contact with said ball if the knob 23 is turned but bysaid ball said head is spaced above the table in such position as toprevent passage of the dog A thus effectually resisting rotation of theshank 29 or retraction of the bolt.
